Clause 11 explained: this guide covers what it means, who it applies to, the step-by-step process, documents required, fees, due dates and penalties in India — so you can stay compliant with confidence and avoid costly mistakes.
Clause 11 has three parts: the books prescribed under section 44AA and Rule 6F, the books actually maintained and the addresses where they are kept, and the books and relevant documents the auditor examined.
From the ICAI Guidance Note on Tax Audit (Revised 2026), the concluding edition under the Income-tax Act, 1961. Under the Income-tax Act, 2025 the books-of-account requirement sits in rule 46 of the Income-tax Rules, 2026 — which renumbers the medical daily case register from Form 3C to Form No. 25 — and the audit particulars move to Form No. 26 under rule 47.
What "books of account" means
Paragraph 23.1 quotes section 2(12A): "books or books of account" includes ledgers, day-books, cash books, account-books and other books, whether kept in the written form or in electronic form or in digital form, or as print-outs of data stored in such electronic or digital form, or in a floppy, disc, tape or any other form of electro-magnetic data storage device.
Clause 11(a) — books prescribed
Paragraph 23.2 states the point most often got wrong at clause 11: under section 44AA read with Rule 6F, books of account have been prescribed only in respect of persons carrying on a specified profession. No books of account have been prescribed for persons carrying on business or a non-specified profession.
Paragraph 23.4 sets out the Rule 6F requirement. Every person carrying on the legal, medical, engineering or architectural profession, or the profession of accountancy, technical consultancy, interior decoration, authorised representative or film artist, whose total gross receipts exceed Rs 1,50,000 in all the three years immediately preceding the previous year — or, where the profession is newly set up, whose gross receipts for that year are likely to exceed that amount — must maintain:
- Cash book
- Journal, if the accounts are maintained according to the mercantile system
- Ledger
A person carrying on the medical profession must additionally keep:
- a daily case register in Form No. 3C showing the date, patient's name, nature of professional services rendered, fees received and date of receipt; and
- an inventory under broad heads, as on the first and the last days of the previous year, of the stock of drugs, medicines and other consumable accessories used for the profession.
Paragraph 23.5 is explicit: the daily case register and the inventory under broad heads do not constitute books of account and hence need not be mentioned under clause 11(a). Where an assessee carries on multiple activities and books have been prescribed for only one of them, mention may be made of the activity for which books have been prescribed.
Paragraph 23.7 completes the statutory picture. Section 44AA(2) requires persons other than those in sub-section (1) to keep such books and documents as may enable the Assessing Officer to compute total income, where income or turnover exceeds the prescribed monetary limits in any one of the three preceding years. Although the CBDT is empowered under section 44AA(3) to prescribe books for such persons, so far no books of account have been prescribed.
Clause 11(b) — books maintained and where they are kept
Paragraph 23.6: the tax auditor should obtain from the assessee a complete list of books of account and other documents maintained — both financial and non-financial records — and make appropriate marks of identification to ensure identification of the books and records produced for audit.
Paragraph 23.8 supplies the practical baseline. For an assessee audited under another law, the maintenance requirement is in that statute. For others, the normal books are cash book or bank book, sales and purchase journal or register, and ledger. Assessees engaged in trading or manufacturing should also maintain quantitative details of principal items of stores, raw materials and finished goods. Where stock records are not properly maintained because of the nature, level, volume and variety of items or transactions, the auditor has to consider materiality and practicality while reporting in Form No. 3CB.
Computerised books
Paragraph 23.9: for books generated by a computer system, the auditor should obtain a list of books generated by the computer system, verifiable from the printout obtained from the assessee. Only such books and records as properly come within the expression "proper books of account" should be mentioned. Section 4 of the Information Technology Act, 2000 supports this: a requirement that information be in writing, typewritten or printed is deemed satisfied if it is rendered or made available in an electronic form and accessible so as to be usable for a subsequent reference.
Locations
Paragraph 23.10: the address at which the books are kept is required. Where books are kept at more than one location, the address of each location with the books maintained there must be given. The recommended working paper format is:
| Sr. No. | Principal place of maintenance of books of account | Details of books maintained |
|---|---|---|
| 1 | Registered office | Ledger, cash book, journal |
| 2 | Factory | Stores and production records |
For a company assessee, the auditor should also verify whether any forms are filed under the Companies Act for maintenance of books at a place other than the registered office.
Paragraph 23.11: where books are maintained and generated through a computer system, obtain the address of the place where the server is located, or the principal place of business, head office or registered office by whatever name called. Where the books are stored on cloud or online, the unique IP address may be reported. The auditor should also verify which books are maintained in the computer system and which records are maintained in hard copy.
Clause 11(c) — books and documents examined
Paragraph 23.12: books examined constitute the books of original entry and the other books of account. In addition, the nature of relevant documents examined must be mentioned. The assessee is required to maintain evidence such as bills, vouchers, receipts, debit notes, credit notes, inventory register, agreements and orders, which the auditor generally examines. The underlying documents differ from assessee to assessee depending on the nature of activity.
Paragraph 23.13 draws the distinction between the two sub-clauses of clause 11: 11(b) is a list furnished by the assessee of books maintained and where they are kept; 11(c) is the auditor's own statement of the books and relevant documents he examined.
"Incorrect reporting was noticed under this clause, including reporting prescribed books of account where none were prescribed, failure to report the location and mode of maintenance of books of account, and omission to report relevant supporting documents and records examined during the course of the audit." All three failures are avoidable: books are prescribed only for a Rule 6F specified profession; 11(b) needs an address and the mode; and 11(c) needs the actual document types examined, not a repetition of 11(b).
When the three lists in clause 11 differ
Paragraph 23.3: there may be differences between the books prescribed, maintained and examined — for instance, books may have been prescribed but not all maintained, or the books maintained may not all have been produced for examination. The tax auditor should exercise professional judgment on whether such a situation warrants disclosure or qualification while forming his opinion on the matters covered by Form No. 3CB.
Worked example
| Assessee | 11(a) prescribed | 11(b) maintained | 11(c) examined |
|---|---|---|---|
| Practising doctor, receipts Rs 90 lakh | Cash book, journal, ledger (Rule 6F). Not the daily case register | Those three, plus the Form 3C register and drug inventory; kept at the clinic; accounting package server at the clinic | The books plus receipts, fee counterfoils, drug purchase bills |
| Trading company, turnover Rs 30 crore | None prescribed | Cash book, bank book, sales and purchase registers, ledger, stock records; registered office and two godowns; books in the cloud, IP address reported | The books plus bank statements, GST returns, TDS returns, purchase and sale agreements |
Audit checklist
- Answer clause 11(a) "none prescribed" unless the assessee carries on a Rule 6F specified profession above the Rs 1,50,000 threshold.
- Exclude the daily case register and drug inventory from the prescribed books list.
- Obtain a complete list of financial and non-financial records and mark them for identification.
- Report every location with the books kept there; for a company, check the Companies Act filing for an alternate location.
- Report the server address, or the IP address where books are on cloud, and which records are on paper.
- List the document types actually examined at clause 11(c) — not a copy of 11(b).
- Where the prescribed, maintained and examined lists diverge, decide whether to disclose or qualify.
Common mistakes
- Listing prescribed books for a business assessee, where none are prescribed.
- Including the Form 3C daily case register as a prescribed book.
- Giving one address where books are kept at several locations.
- Omitting the server or cloud location for computerised books.
- Repeating the 11(b) list at 11(c) without naming the supporting documents examined.
